Maybe it's because I played Saints Row 3 within a year or so of SR2 but I was fairly let down. The campaign missions were fairly short and the activities were carbon copies from the second. Questioning whether I'd buy 4 even at some $5 bargain price -- especially considering it is more like SR 3.5 than SR4.
Played, and near 100%ed, during the free weekend and this is pretty much like baturinsky said. It's a fun (but VERY short) game, but hardly a Saints Row game outside of a few parts where they are directly referencing the first 3. Very much worth paying 5 bucks for when the "complete" version hits that price.
Still, the fact that it iis actually a fairly good game instead of a complete piece of shit like 3 (most of the jokes are actually funny this time) gives me hope 5 (which Dane Vogel's voice actor confirmed) will at least be comparable to 2.
